Refuge versus dispersion in the logistic equation

Abstract: In this paper we consider a logistic equation with nonlinear diffusion arising in population dynamics. In this model, there exists a refuge where the species grows following a Malthusian law and, in addition, there exists also a non-linear diffusion representing a repulsive dispersion of the species. We prove existence and uniqueness of positive solution and study the behavior of this solution with respect to the parameter λ, the growth rate of the species. Mainly, we use bifurcation techniques, the sub-supers… Show more

“…The difference is that the Law wants to punish dishonest and corrupt public agents, but prefers to leave out those who act with incompetence and unpreparedness (Cintra;Spaziante, 2022). In a way, the Courts of Justice had the notion of the need to specify the specific intentional modality of administrative improbity, the intention being bad faith.…”
